1.Immune effects of a precocious line of Eimeria necatrix with different doses and at different immunization times
Tropical Biomedicine 2016;33(3):570-576
This study was designed to assess the immune protective effects of the vaccine
strain of a precocious line of Eimeria necatrix with different doses and at different
immunization times. The immunizations had a negative effect on weight gains of chickens to
a certain degree but could be compensated during the “compensatory growth period” after
immunity was established in the chickens. The number of oocysts excreted was positively
correlated with the immunization dose. All the immunized chickens, whether they were
immunized once or twice or immunized with different doses of sporulated oocysts, were able
to resist attack from 1x105 virulent sporulated oocysts of E. necatrix. The lesion scoring
showed that no significant difference existed in the chicken groups immunized with different
doses (300 and 600) of sporulated oocysts. However, a difference existed in the immune
homogeneity established in the different immunized groups, and two artificial immunizations
were superior to one artificial immunization, indicating that two could extend the duration of
oocyst excretion and allow more chances for the immunized chickens to become repeatedly
infected.

ObjectiveTo analyze the relative influential factors of hearing rehabilitation of the deafened children with multichannel cochlear implant. Methods42 prelingually deafened children who accepted multichannel cochlear implant were evaluated with their hearing ability, hearing thresholds and talent level, while their family and usage of the multichannel cochlear were investigated. Results and ConclusionThe result shows that the factors influencing the hearing rehabilitation are the occupations of the parents, income of the family, the time between diagnosing deaf and the operation, the time after the cochlear implant operation and the talent level. The results of the logistic regression show that the deafened children can gain their hearing developing rapidly if they living in a family with high income, their mothers have accepted more education, and they accepted longer time of continuing hearing-aid, etc.

OBJECTIVE:
To observe waveform differences among ocular vestibular evoked myogenic potentials (ACS-oVEMP) elicited by different types of air conducted sound in normal young Chinese subjects.
METHOD:
Twenty-two adult volunteers (44 ears) were recruited as research subjects including 12 males and 10 females aged between 18 and 35. Five hundred Hz tone burst, 125 Hz tone burst and click were employed as stimulus for conventional ACS-oVEMP examinations in bilateral ears of each subject. The response rate, threshold, n I latency, p I latency, n I-p I latency interval, amplitude and inter-aural asymmetry were recorded and compared among groups.
RESULT:
The response rate was 100% (44/44) in 500 Hz tone burst group, 40.9% (18/44) in 125 Hz tone burst group and 29.6% (12/44) in click group There were statistical significant differences between the 500 Hz tone burst group and the other groups (P < 0.05). Waveform amplitude was the largest in the 500 Hz tone burst group (7.3 +/- 5.5) muV than that in the 125 Hz tone burst group (3.8 +/- 1.5) muV and that in the click group (5.8 +/- 1.3) muV, which had statistically significant differences between the former and the later two groups (P < 0.05). Other waveform parameters presented similar differeces.
CONCLUSION
ACS-oVEMP waveforms could be largely affected by different stimulus. 500 Hz tone burst was the best stimulus with highest response rate, biggest amplitude and therefore most easily recognizable waveform in ACS-oVEMP examination.

Objective To explore the most accurate T staging and optimal surgical method of lung adenocarcinoma of trans-lobe type, and to provide supportive diagnosis as well as therapeutic evidences for this disease. Methods A total of 192 postoperative patients, hospitalized in Tianjin Medical University General Hospital from January 2008 to June 2013, who were diagnosed with lung adenocarcinoma were recruited. Patients were divided into three groups according to the 7th edition of TNM staging criteria issued by the IASLC in 2009. A total of 163 patients with T2 stage were selected as Group T2, and 12 patients with T3 stage were selected as Group T3, both of which were considered as control groups. Other 17 pa?tients who were diagnosed as trans-lobe type of lung adenocarcinoma, were Group trans-lobe. The clinical data and progno?sis were compared between three groups. The trans-lobe type of lung adenocarcinoma was diagnosed based on imaging and pathological examination. Subtypes of trans-lobe lung adenocarcinoma were identified by referring to 2011 international mul?tidisciplinary classification standard of lung adenocarcinoma. Kaplan-Meier method was used to analyze the prognosis of dif?ferent subtypes and surgical modus in patients with lung adenocarcinoma of trans-lobe type. Results By comparison, the postoperative survival rate was significantly lower in patients diagnosed with trans-lobe type of lung adenocarcinoma than that of Group T2 (P<0.05), and no significant difference in survival rate compared with Group T3 (P>0.05). There were no significant differences in survival rates between different surgical modus (P<0.05). Seventeen patients with trans-lobe type of lung adenocarcinoma consisted of four subtypes, including 8 solid predominant, 5 acinar predominant, 3 papillary predomi?nant and 1 invasive mucinous adenocarcinoma. There were no statistical significances in postoperative survival time and sur?vival rates between four subtypes. Conclusion The clinical stage of trans-lobe type of lung adenocarcinoma should be clas?sified as stage T3. Both pulmonary bilobectomy and lobectomy combined with resection of proximal invaded lobe can be used as effective surgical therapies for trans-lobe type of lung adenocarcinoma.

Objective To investigate the immunological characteristics and clinical significance of reactive plasmacytosis in patients with severe fever with throbocytopenia syndrome (SFTS).Methods Bunyavirus-infected patients who were diagnosed with SFTS were collected from March 2015 to October 2015 in Taizhou Hospital.Morphology analysis of bone marrow and peripheral blood (PB) smear, as well as flow cytometry analysis of plasma cell immune phenotype from peripheral blood were conducted.Serum immunoglobulin levels and helper T hymphocytes (Th)1/Th2 cytokine expressions were detected.Mann-Whitney U test was used.Results PB plasma cells from all of the SFTS patients increased in varying degrees, and the phenotype of the plasma cells was CD19+CD38++CD45+CD138+, which indicated normal mature plasma cells.The ratio of PB plasma cells was >0.030 in 10/16 patients, and >0.300 in 2/16 patients.The ratios of PB plasma cells in the patients with severe and critical groups were significantly higher than that in the mild group (0.052 vs 0.016, P<0.05).Monocytoid histiocytes and hemophagocytes were observed in the BM morphology of 9 patients.Three of them were diagnosed as hemophagocytic lymphohistiocytosis (HLH).The ratio of plasma cells was more than 0.030 in the bone marrow of 8 patients.The serum levels of interlewkin (IL)-6, IL-10 and interferon (IFN)-γ in acute phase were significantly elevated with the median level of 49.75 ng/L, 26.98 ng/L (reference value 2.6 to 4.9 ng/L) and 17.57 ng/L, respectively.While the levels of IL-2, IL-4 and twmor necrosis fautor(TNF)-α were not significantly changed.The serum IL-6 and IL-10 levels in the patients with severe and critical groups were both significantly higher than those in the mild group (IL-6: 132.36 vs 22.81 ng/L;IL-10: 75.28 vs 6.33 ng/L, both P<0.05), but the difference of IFN-γ level was not significant (P>0.05).The serum IgG, IgA and IgM levels did not increase in acute stage, with the median of 11.6 g/L, 2.56 g/L and 1.60 g/L (reference value 0.46 to 3.04 g/L), respectively.Conclusion The patients with SFTS show excessive humoral and cellular immunity, and the severity of disease is positively correlated with the ratio of peripheral plasma cells and the levels of cytokines IL-6 and IL-10.
